10¹¹ meters = 100,000,000 kilometers

You are now seeing the Inner Solar System and the orbits traced out by Mercury, Venus, Mars, and Earth. Our home world orbits the sun at an average distance of 150 million kilometers (93 million miles).

The region between the planets is mainly empty space. There are some particles of dust and molecules of gas very sparsely sprinkled between the worlds. But there are also a few thousand small asteroids that have come together from the material left over from the formation of the inner planets.
